Ae Freslighe (ay fresh lee) is a Celtic form of poetry:

Each stanza is a quatrain of seven syllables. Lines one and three rhyme with a triple (three syllable) rhyme and two and four use a double (two syllable) rhyme. The poem should end with the first syllable word or the complete line that it began with.

x x x x (x x a)
x x x x x (x b)
x x x x (x x a)
x x x x x (x b)

It may be more than one quatrain (as mine is here). 
 
The scheme: 
 
x x x x (x-x-a) 
x x x x x (x-b) 
x x x x (x-x-a) 
x x x x x (x-b) 

Here is one of mine:

Whispered

Whisper while I ‘m abstaining
from such things that might disturb
those who lie of love, feigning...
my love will shout and  reverb.

Shower with me, alluring,
photograph doctored slightly;
a poem to be assuring,
showing love - dried off lightly.

Freshly taste me, preserving
things fresh and ever-crisper;
sense that I am conserving?
love through senses has whispered.
